Note 1: “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed. They are not meant to imply that the devices
should be operated at these limits. The table of “Electrical Characteristics” specifies conditions of device operation.
Note 2: Current into device pins is defined as positive. Current out of device pins is defined as negative. All voltages are referenced to ground except: V
OD1
and
∆V
OD1
.
Note 3: All typicals are given for: V
CC
= +5.0V, T
A
= +25˚C.
Note 4: Channel-to-Channel Skew is defined as the difference between the propagation delay of the channel and the other channels in the same chip with an event
on the inputs.
Note 5: Chip to Chip Skew is defined as the difference between the minimum and maximum specified differential propagation delays.
Note 6: Generator waveform for all tests unless otherwise specified:f=1MHz, Z
O
=50Ω,t
r
≤6 ns, and t
f
≤ 6 ns.
Note 7: ESD Ratings:
HBM (1.5 kΩ, 100 pF) ≥ 3,500V
EIAJ (0Ω, 200 pF) ≥ 250V
Note 8: Output short circuit current (I
OS
) is specified as magnitude only, minus sign indicates direction only.
Note 9: C
L
includes probe and jig capacitance.
Note 10: Guaranteed by characterization data (DS90C031E).
